Description
CROSS-REFERENCE TO RELATED APPLICATION
[0001] This application claims priority to and incorporates herein
Chinese Application No. 201520593402.7 filed on Aug. 7, 2015.
TECHNICAL FIELD
[0002] The present disclosure relates to the field of lamps and
lighting, in particular to an embedded LED lamp.
BACKGROUND
[0003] LEDs have the advantages of saving energy, being
environmentally friendly, having a long life, and having a small
size. As such, they have been referred to as the fourth generation
light source or green light. They are widely used in various fields
relating to guideboards, displaying, decoration, backlights,
general lighting, and urban landscaping.
[0004] Currently, LEDs are combined with reflectors according to
needs of a particular application. The combination of a reflector
and a lens makes light from a LED lamp richer, softer, and more
uniformly emitted, so as to protect eyes. Moreover, it is desirable
to uniformly scatter light emitted from LEDs through a lens while
avoiding energy dissipation within the reflector, such that (1)
users cannot see light beads and (2) that a maximum amount of light
can be provided. In addition, LED lamps are in great demand and
need to be adapted to a variety of applications. It is therefore
particularly important to be able to conveniently assemble LED
lamps.
[0005] Notwithstanding the above, LED lamps made with existing
technology are complicated, with high manufacturing cost and
inconvenient assembling. Accordingly, it is desirable to provide a
new LED lamp.
SUMMARY
[0006] In view of the above, an object of the present disclosure is
to provide an embedded LED lamp to address the problems of
complicated structure, high manufacturing cost, and inconvenient
assembly of LED lamps made with existing technology.
[0007] In one example, an embedded LED lamp includes a power supply
device, a lampshade, an LED light module, a reflector, and a lens.
The power supply device includes a cup-shaped housing and a power
supply unit provided within the housing. An opening end of the
housing is detachably connected to an outer side of a bottom
surface of the lampshade. The reflector is positioned within the
lampshade. The reflector is detachably connected to an inner side
of the bottom surface of the lampshade. A large opening at a front
end of the reflector is detachably connected to the lens. The LED
light module is attached at the inner side of the bottom of the
lampshade in an area surrounded by an opening at a rear end of the
reflector.
[0008] In another example, the embedded LED lamp further includes a
lamp ring, which is matched and assembled with an opening of the
lampshade.
[0009] In yet another example, the embedded LED lamp further
includes a spring securing element and a metal torsion spring. The
spring securing element has a fixing portion, a connecting portion,
and a snap-fit portion. The fixing portion, the connecting portion,
and the snap-fit portion are integrally formed. The fixing portion
is detachably connected to the outer side of the bottom surface of
the lampshade. The connection portion extends from the fixing
portion and is connected to or fitted with a side wall of the
lampshade. The snap-fit portion extends from the connection portion
and includes snap-fit collar. The metal torsion spring is provided
in the snap-fit collar.
[0010] In yet another example, the fixing portion is provided with
a hook portion. A curvature of the connecting portion is
substantially the same as that of an outer side of the side wall
the lampshade. The snap-fit portion comprises a first snap-fit
portion and a second snap-fit portion extending from the first
snap-fit portion. A cross-section of the snap-fit portion is
S-shaped; and a cross-sectional radius of the first snap-fit
portion is not equal to that of the second snap-fit portion.
[0011] In yet another example, the metal torsion spring is formed
by two small coils and a large coil. Each of the two small coils
and the large coil are coiled separately. The large coil is located
between the two small coils. A first torsion arm and a second
straight torsion arm extend from the two small coils, respectively,
toward a same side.
[0012] In yet another example, the lampshade is made of a
conductive material and the side wall of the lampshade is
threaded.
[0013] In yet another example, the outer side of the bottom surface
of the lampshade is provided with a positioning groove. The housing
and the spring securing element are respectively engaged with
opposite sides of the positioning groove.
[0014] In yet another example, an outer side of the side wall of
the reflector is provided with a plurality of evenly spaced
cylinders. A plurality of projections are provided on bottom
surface of the lampshade at positions that correspond to those of
the cylinders. The cylinders and projections have threaded holes
and are configured to be respectively attached with screws.
[0015] In yet another example, the power supply device further
comprises a push-in terminal and the push-in terminal is connected
to the power supply unit.
[0016] In yet another example, the cross-section of lamp ring is
arc-shaped.
[0017] Compared with the prior art, an embedded LED lamp of the
present disclosure, a power supply unit, and a LED light module are
separated from each other, increasing the space for heat
dissipation and the paths for heat dissipation. In this way, the
effect of heat on the power supply device may be reduced. The
embedded LED lamp will have less light loss, good heat dissipation,
and provide softer light. Further, the disclosed embedded LED lamp
is simple, with low manufacturing costs and convenient
assembly.
[0018] It is to be understood that both the foregoing general
description and the following detailed description are exemplary
and explanatory only and are not restrictive of the invention, as
claimed.

DETAILED DESCRIPTION
[0028] References will now be made in detail to the present
exemplary embodiments, examples of which are illustrated in the
accompanying drawings. Wherever possible, the same reference
numbers will be used throughout the drawings to refer to the same
or like parts. While the description includes exemplary
embodiments, other embodiments are possible, and changes may be
made to the embodiments described without departing from the spirit
and scope of the invention. The following detailed description does
not limit the invention. Instead, the scope of the invention is
defined by the appended claims and their equivalents.
[0029] FIG. 1 depicts an embedded LED lamp according to the present
disclosure. The embedded LED lamp 1 may include a power supply
device 10, a lampshade 20, a LED light module 30, a reflector 40,
and a lens 50. The power supply device 10 comprises a cup-shaped
housing 11 and a power supply unit 12 provided within the housing
11. The opening end of the housing 11 is detachably connected to
the outer side of the bottom of the lampshade 20. The reflector 40
is located within the lampshade 20, and the small opening 41 end of
the reflector 40 within the lampshade 20 is detachably connected to
the inner side of the bottom of the lampshade 20. The large opening
43 end of the reflector 40 is detachably connected to the lens 50.
The LED light module 30 is fixed at the inner side of the bottom of
the lampshade 20 in an area that is surrounded by the opening end
of the housing 11.
[0030] In some embodiments, the reflector 40 has a bottom surface
at its rear end. In such embodiments the LED light module 30 may be
fixed at the inner side of the bottom surface of the rear end of
reflector 40.
[0031] The opening end of the housing 11 may be affixed to the
outer side of the bottom surface of the lampshade 20 via screws,
and constitutes an enclosed space along with the bottom surface of
the lampshade 20. The power supply unit 12 is provided on the inner
wall of a side of the housing 11 that is away from the lampshade
20, ensuring a stable power supply so that the embedded LED lamp
can work smoothly. The LED light module 30 is provided on the
inside of the bottom surface of the lampshade 20, which is away
from the power supply device 10. In this way, the power supply unit
12 and the LED light module 30 are spaced away from one another.
Thus, the power supply unit 12 is unlikely to be adversely affected
by the heat from the LED light module 30, thereby extending the
life of the power supply unit. The reflector 40 is substantially
trumpet-shaped with a small opening 41 end and large opening 43
end. The small opening 41 end of reflector 40 surrounds the area
where the LED light module 30 is located and is fixed to the inner
side of the bottom of the lampshade 20, such that the light emitted
from LED light module 30 can only travel out through the large
opening 43 end of the reflector 40. The lens 50 is snap-fitted in
the large opening 43 end of the reflector 40. In this embodiment,
the reflector 40 can make light become soft, and the soft light
travels through the lens 50 so that the light can be uniformly
dispersed. The whole reflector 40 may be located inside the
lampshade 20. Light passes through the lens 50 and may be further
uniformly and softly dispersed by the lampshade 20.
[0032] In the embedded LED lamp of the present disclosure, the
power supply unit 12 and the LED light module are respectively
enclosed in separate spaces by housing 11 and lampshade 20. Part of
the role of a bulb of a conventional lamp is accomplished by a
combination of the trumpet-shaped reflector 40 and the lens 50
provided at the large opening end of the reflector 40. The emitted
light is softened and evenly dispersed though this configuration.
The LED lamp has a larger space for heat dissipation and less light
loss than a conventional lamp. Its structure is simple, with low
manufacturing cost and convenient assembly.
[0033] FIG. 2 depicts lampshade 20 of an embodiment of the embedded
LED lamp according to the present disclosure. FIG. 3 depicts
reflector 40 of an embodiment of the embedded LED lamp according to
the present disclosure. FIG. 4 depicts spring securing element 60
of an embodiment of the embedded LED lamp according to the present
disclosure. FIG. 5 depicts metal torsion spring 70 of an embodiment
of the embedded LED lamp according to the present disclosure. FIG.
6 depicts lamp ring 80 of an embodiment of the embedded LED lamp
according to the present disclosure.
[0034] In a preferred embodiment, as shown in FIG. 2, the lampshade
20 is substantially bowl-shaped. The bottom surface of the
lampshade 20 is substantially flat, and is provided with three
projections 21 and two positioning grooves 22. The three
projections 21 are located on the outside of the bowl shape and are
co-circular to each other such that the arc between any two
projections 21 measures 120.degree.. The positioning grooves 22 may
be provided near the periphery of the bottom of the lampshade 20,
external to the projections 21 with respect to the center of the
bottom of the lamp shade 20. One of the positioning grooves 22 may
be next to one of the projections 21. The positioning grooves may
be positioned such that the features of the bottom surface of the
lampshade 20 may be symmetrical, with respect to projections 21 and
positioning grooves 22. The diameter of the side wall 23 of
lampshade 20 gradually expands from the bottom surface of lampshade
20 toward the opening, and the side wall 20 has a thread structure.
A matching portion 24 is provided on the side wall 23 at the
opening of the lampshade 20. The matching portion 24 extends
outside the side wall opening substantially parallel to the bottom
surface of the lampshade 20.
[0035] As shown in FIG. 3, and discussed above, the reflector 40 is
trumpet-shaped with a small opening 41 and a large opening 43. The
outside of the wall of the reflector 40 is provided with three
cylinders 42, which are configured to correspond to the three
projections 21 when the reflector 40 is assembled within lampshade
20. In the present embodiment, the projections 21 and the cylinders
42 all have threaded holes, and may be joined together by screws.
The small opening 41 of the reflector 40 has a flat circular edge,
which is at the same level as the ends of the cylinders 42. The
outside of the reflector 40 is evenly provided with a plurality of
slots 44 near the large opening 43.
[0036] As shown in FIG. 4, the spring securing element 60, which
may be a metal elastic piece, has a fixing portion 61, a connecting
portion 62, and a snap-fit portion 63, which are preferably
integrally formed. The end of the fixing portion 61 that is distal
from the connecting portion 62 is provided with a hook portion 611,
which extends and forms an angle of 90.degree. with the body of the
fixing portion 61. The connecting portion 62 extends at an angle
from the non-hook end of the fixing portion 61. The connecting
portion 62 has the shape of a convex arc. The curvature of the
connecting portion 62 is substantially the same with that of the
outer side of the side wall 23 the lampshade 20. The snap-fit
portion 63 extends from the connecting portion 62 away from the end
of the fixing portion 61 and is preferably snap-fit collar that may
be cylindrical.
[0037] The snap-fit portion 63 comprises a first snap-fit portion
631 and a second snap-fit portion 632, which extends from the first
snap-fit portion 631. The cross-section of the snap-fit portion 63
is S-shaped, and the cross-sectional radius of the first snap-fit
portion 631 is larger than that of the second snap-fit portion 632.
A small gap is formed between the second snap-fit portion 632 and
the connecting portion 62 for the metal torsion spring 70 to pass
through. The end of the second snap-fit portion 632 extends
outwardly. In other embodiments, the cross-sectional radius of the
first snap-fit portion 631 may be less than or equal to that of the
second snap-fit portion 632.
[0038] As shown in FIG. 5, the metal torsion spring 70 is formed by
a first small coil 71, a large coil 73, and a second small coil 72,
which are separately coiled in sequence. Among the coils, the large
coil 73 may include a plurality of turns that are close to each
other. A first straight torsion arm 74 extends from the first small
coil 71, a first fixing hook portion 75 is provided at the end of
the first straight torsion arm 74. A second straight torsion arm 76
extends from the second small circle 72, a second fixing hook
portion 77 is provided at the end of the second straight torsion
arm 76. The first straight torsion arm 74 and the second straight
torsion arm 76 expand and extend toward a same side at an angle
from each other.
[0039] As shown in FIG. 6, the lamp ring 80 is circular, and the
inner edge of a first side of the lamp ring 80 is provided with an
annular groove 81.
[0040] The connection relationships among different components in
the embedded LED lamp of the present utility model are further
explained with references to FIGS. 1-6.
[0041] The screw holes for the three cylinders 42 provided at the
back of the reflector 40 are disposed corresponding to the screw
holes of the three projections 21 of the lampshade 20. The
cylinders 42 and the projections 21 may be fixed together through
screws, so that the small opening 41 of the reflector 40 may be
secured the inner side of the bottom of the lampshade 20. The LED
light module 30 is fixed at the inner side of the bottom of the
lampshade 20 in the area surrounded by the small opening 41 of the
reflector 40.
[0042] As discussed, the outside of the bottom surface of lampshade
20 is provided with two positioning grooves 22 in a preferred
embodiment. The housing 11 is engaged at an inner side of the
positioning grooves 22, which is closer to the center of the
lampshade 20. The fixing portion 61 of the spring securing element
60 is engaged at an outer, opposite side of the respective
positioning grooves 22, which is closer to the outer edge of the
lampshade 20, with the hook portions 611 extending into the grooves
22. When the hook portions 611 extend into the respective
positioning grooves 22, the connecting portion 62 may be connected
to or fitted with the outer side wall 23 of the lampshade 20. At
this time, the second small coil 73 of the metal torsion spring 70
can be passed through the small gap formed between the second
snap-fit portion 632 and the connecting portion 62, so that the
metal torsion spring 70 can swing freely.
[0043] The outer edge of the lens 50 are provided with protrusions
that correspond to with the plurality of slots 44 of reflector 40,
such that the lens 50 may be snap-fitted on the larger opening 43
of reflector 40.
[0044] Before assembling the spring securing element 60 and the
metal torsion spring 70, assembly may require positioning the lamp
ring 80 with the side of the lamp ring 80 that has the annular
groove 81 facing downward. The lamp ring may sequentially be placed
over the housing 11 (with the housing 11 opening facing downward)
and the lampshade 20 (with the lampshade 20 opening facing
downward), until that the annular groove 81 abuts against the
matching portion 24 of the lampshade 20. The depth of the annular
groove 81 may be greater or equal to the thickness of the matching
portion 24, so that the lamp ring 80 and the lampshade 20 have a
smooth connection after the lamp ring 80 is positioned on the
matching portion 24.
[0045] In alternative embodiments, the matching portion 24 may
include an annular groove, and the lamp ring 80 may include a
corresponding protrusion, so that a groove of the matching portion
24 and the protrusion of a lamp ring 80 would correspond during
assembly.
[0046] In the embedded LED lamp of the present disclosure, during
assembling, the lampshade 20 can be directly placed at the center
through the annular groove 81. In some embodiments, a cross-section
of lamp ring 80 may be arc-shaped, enhancing the aesthetic view of
the embedded LED lamp. The arc is preferably provided on the second
side of the lamp ring 80, opposite from the annual groove 81. The
color of the lamp ring 80 can be changed with a variety of
choices.
[0047] In the embedded LED lamp of the present disclosure, the
embedded LED lamp can be assembled with different types of light
tubes 2 via the presence of at least one pair of a spring securing
element 60 and a metal torsion spring 70. As shown in FIGS. 1 and
7, more than one pair of a spring securing element 60 and a metal
torsion spring 70 may be used. The fixing portion 61 of the spring
securing element 60 is provided with a hook portion 611, the
curvature of the connecting portion 62 is substantially the same
with that of the outer side of the side wall the lampshade 20, and
the cross-section of the snap-fit portion 63 is S-shaped. These
characteristics may help make the assembling and disassembling of
the spring securing element 60 and the metal torsion spring 70
simple and convenient.
[0048] In the embedded LED lamp of the present disclosure, the
metal torsion spring 70 is composed of two small coils and a large
coil that are coiled separately. The large coil is disposed between
the two small coils and two straight torsion arms extend from the
two small coils toward a same side at an angle from each other.
This permits the first straight torsion arm 74 and the second
straight torsion arm 76 to simultaneously exert pressure in
opposite directions, facilitating assembling of the embedded LED
lamp with different types of light tubes 2.
[0049] In the embedded LED lamp of the present disclosure, the side
wall 23 of the lampshade 20 is threaded, which endows the lampshade
20 with a more decorative feature, prevents light refraction, gives
anti-glare effect, and can increase the heat dissipation area for
better cooling effect. In addition, the lampshade 20 may comprise
thermally conductive materials such as aluminum, which can further
enhance the heat dissipation effect.
[0050] In the embedded LED lamp of the present disclosure, the
outer side of the bottom of the lampshade 20 is provided with at
least one positioning groove. In this way, the housing 11 can
conveniently avoid the spring securing element 60 while being
secured to the outer side of the bottom surface of the lampshade
20. This facilitates assembly of an embedded LED lamp.
[0051] In the embedded LED lamp of the present disclosure, the
outer side of the side wall of the reflector 40 is provided with a
plurality of evenly spaced cylinder 42, and a plurality of
projections 21 are provided at the positions of the lampshade 20
that correspond to those of the cylinders 21, which makes it more
convenient to assemble the reflector 40 at the inner side of the
bottom of the lampshade 20.
[0052] The working principles of the embedded LED lamp according to
the disclosure may be described with reference to FIGS. 7 and 8.
FIG. 7 depicts an embedded LED lamp of the present disclosure and a
light tube before installation. FIG. 8 depicts the connection of a
metal torsion spring 70 and the light tube after installation of
the embedded LED lamp of the present utility model and a light
tube.
[0053] In this embodiment depicted in FIG. 7, the power supply
device 10 further comprises a push-in terminal 13. After assembling
an embedded LED lamp, the push-in terminal 13 and the power supply
connector 3 of light tube 2 are connected.
[0054] Next, the user can manipulate the first straight torsion arm
74 and the second straight torsion arm 76 simultaneously in toward
one another, against the force of the spring, so that the first
straight torsion arm 74 and the second straight torsion arm 76 are
close to each other. Then, then the first straight torsion arm 74
and the second straight torsion arm 76 can be inserted into the
light tube 2. The inserted first straight torsion arm 74 and second
straight torsion arm 76 are adjusted, so that the connection
portion between the first straight torsion arm 74 and the first
fixing hook portion 75 and the connection portion between the
second straight torsion arm 76 and the second fixing hook portion
77 are fitted in a support 4 of the light tube 2.
[0055] Finally, the embedded LED lamp is pushed into the light tube
2, so that the embedded LED lamp is fully installed in light tube
2.
[0056] An embedded LED lamp can be conveniently connected with
different types of light tubes 2, due to, for example, the presence
of the push-in terminal 13, the spring securing element 60, and the
metal torsion spring 70, 2.
